USSutcliffe Electronics have been in business in Ashford Kent for over 30 years. We are a small electronics manufacturer which specialises in Wired Beam type infrared Driveway Alarms. Our Driveway Alarm is designed for self fit by the customer, and does not require an electrician. Most of our products are biased towards the farming community, but just because you do not own a farm or smallholding, is not a reason for not wanting to know whether someone is coming up your drive.

Driveway alarms from Sutcliffe Electronics

We manufacture and sell active beam type security alarms

An active infra red wired beam device to give warning of a visitor on your property, and which can also be used to trigger a warning siren, page you with a portable radio, of switch on flood lights.The Infra red beam consists of a sender and a receiver, which are mounted on either side of the drive. Both are connected to the Control box, which provides 12V power for the system, and is plugged into the 240V mains in the house.The Control box has integral 13A plug pins, and contains adjustable timing for an internal buzzer, a Delay timer, and on On timer and transistor switch to drive a siren. It can support 3 separate beams, and two extra buzzers. Each beam comes with 100m of cable, (Recommended Maximum Cable 500m) and 2 aluminium mounting brackets. There are 3 knobs, one to adjust the ON time of the buzzer (1--15seconds) and the other two to adjust the DELAY and ON time of a siren. By this means any external alarm is delayed, to prevent the beam position from being marked by a prospective intruder. Similarly the boxes are best mounted IN rather than ON posts in order to hide their position. Hollow posts can be made by nailing 4 boards together.The optimum height for mounting the beam is 0.9m (1 yard), this allows small animals to pass below, but is below the window in a car door. There is a delay in the beam to allow a bird to pass through without causing false triggering. This is set to roughly 1/10 of a second, but is adjustable if it proves too short or too long.No special tools are required to set up the beam, there is a red light on the receiver which helps to centre it. It can be fitted by a competent handy person with the instructions supplied.Sitcliffe Electronics do not produce a reflector model with the sender and receiver on one side of the drive, and a target on the other, since they are much more prone to false alarms and can be easily bypassed.

A device to give warning that your electric stock fence is not functioning correctly. Once the voltage in an electric fence has dropped to about 3000V or below, it is rapidly reaching the point when it is no longer effectivr. The FENCESENSE gives a loud beep when this point is reached, allowing the fault to be rectified before the animals get out (or the Fox to get in).Just hang the FENCESENSE on the electric fence wire, clip the orange lead to the fence, and the green lead to a good earth, switch on and leave.The device is powered from three AA cells which should give a monitoring life of upto a year. (life depends on the quality of the batteries used) If the batteries become low, the red indicator light goes out, and when flat, the beep is activated continuously, this being the fail safe mode.

Trailer security

Telescopic Hitch Post

It is well known that even if wheel clamps and a hitch lock have been fitted, trailers still disappear. One way to protect your valuable asset is to lock it to the ground.Our Telescopic Hitch Post, consists of an outer steel tube, 800mm in length, and an inner telescopic tube of 5mm wall thickness which is designed such that it cannot be removed. This is topped with a 50mm tow ball. The outer tube is sunk into the ground flush, and concreted to make it permanent. One can not do anything easy about the portable angle grinder, but anything which makes it more difficult to take away your trailer will improve your security.The Telescopic Hitch Post takes time and tools to overcome. Your expensive trailer cannot be towed away by just winding a chain round the locked hitch and dragging the wheel clamps until they fall off. We would still recommend that other security is fitted to your site, to give advanced warning that you have an unwanted visitor.
